3 Claims.

This invention relates to defecators i. e., waterclosets, and more particularly todefecators comprising a bowl with rim channel flushing means,

and a storage tank for a flushing liquid, usually water, communicating with the rim-flow-channel of the bowl.

The present invention has as primary objects the elimination of whistling noises usually attending the flushing cycle of the above specified types of defecators, the utilization of practically the entire liquid contents of the storage tank during each flushing cycle, and the provision for a positive after-fill of the well of the bowl, supplied, in a major degree, from the normal liquid contents of the storage tank.

Such objects are accomplished by providing suitable air-venting means for the rim-flowchannel of the defecator bowl during the flushing cycle to prevent entrapment of air therein and thus to eliminate syphonic action commonly operative on the supply stream from the storage tank to effect premature closure of the flush valve.

Pursuant to the present invention, embodiments thereof usually comprise a tank for the storage of flushing-liquid, a defecator bowl provided with a rim-'flow-channel, a discharge conduit leading from the storage tank to the rimflow-channel and operative to originate and 30 maintain a unidirectional flow of flushing liquid around the rim-fiow-channel, an over-flow channel within the storage tank, and means alfording communication between the over-fiow-channel and the rim-flow-channel at a location adjacent the termination of the flow-stream in the rimflow-channel.

Advantageously, embodiments of this invention include a defecator of the type disclosed in my copending application for U. S. patent Serial No. 25,475, filed June '7, 1935, wherein a defecator bowl of the type disclosed in my copending application Serial No. 749,069, filed October 19, 1934 is novelly combined with an evacuator of the gen eral nature of that disclosed in my copending application Serial No. 4,620, filed February 2, 1935. Preferred embodiments incorporate the storage tank integrally with the defecator bowl, and, de sirably, also integrally with the evacuator.

A preferred embodiment of the present invention showing a defecator bowl integrally combined with an evacuator according to the above referred to copending applications, and a storage tank integrally incorporated therewith, is illustrated in the accompanying drawings, in which:

Fig. 1 represents a vertical central section through such embodiment.

Fig. 2 is a top plan view, hidden channels being indicated by dotted lines.

Fig. 3 represents a vertical section taken on the line 33, Fig. 1.

Fig. 4 represents a horizontal section taken on the line 4 4, Fig. 1.

Referring to the drawings and to the therein illustrated embodiment of this invention, the

unitary combination of a defecator bowl ill, a storage tank I l, and an evacuator I2 is of the Wall-hung type and is suitably secured with its substantially planar, Vertical back face 13 against a wall, or equivalent, indicated at M. Such defecator combination discharges laterally through the opening l5 into component piping (not shown) of a waste disposal system.

In the particular embodiment, the rim-flowchannel l6 comprehends the upper periphery of the bowl l0 and has branching therefrom at its front a downfiow channel ll terminating in a main flush-jet orifice I 8 anteriorly of the well IQ of the bowl. Also, branching from the rimflow-channel 16 at an appropriate location is a downflow conduit 20 terminating in the vortexeffecting-jet orifice 2!, located advantageously in an interior wall of the bowl near the maintained surface level 22a, of the liquid after-fill 22. The

rim-flow-channel I6 is provided with a plurality of jet openings 23 spaced along its underside periphery.

The up-fiow leg 24 of the evacuator ill, at its lower end communicates with the well I9 of the bowl I0 at a location opposite post-zriorly the main flush-jet orifice I 3, and at its upper end opens into the down-flow leg 25. Such downfiow-leg communicates with the lateral discharge opening l5.

The lower portion of the upper wall of the upfiow leg 24 advantageously forms the rear wall of the bowl, and the upper wall of the down-flow leg 25 advantageously forms the lower wall of the up-flow leg 24.

The tank I I for the storage of flush liquid rises integrally from the upper portion of the evacuator l2 posteriorly of the defecator bowl I0 and includes preferably integrally therewith the overflow-channel 2G. The bottom wall of the tank I I advantageously forms the top wall of the evacuator I2.

The present invention is concerned primarily with the cooperative relationship of the storage tank, and its therewith included overflow chandisplace the water in such rim-flow-channel by I air at the termination of the-flushing cycle. To this end, embodiments of the present invention provide for unidirectional flow of flushing liquid: around the rim-flow-channel, I and include airvent means proximate the termination of flow of such liquid. The air vent means is advantageously coincident with the over-flow channel in the storage tank. a I

In the particular embodiment of the drawings, a flow passage 30, see Fig.3, affords connection between the storage tank Hand thelrim-flowchannel IB. Such flow passage 30 is advantageously'positioned adjacenta lateral side of' the storage tank for originating and maintaining unidirectional flow around the rim-flow-channel I6. The over-flow-channel-26 is preferably positioned proximate the front wallof the storage tank II. and communicates at its lower end with, and forms an upward extension of, the terminal end I6a of the rim-fiow-channel l6. may separate theterminal end of the rim-flowchannel from the intake or supply end. The

down-flow conduit 20, terminating in-the vortexeffecting-jet orifice 2|, preferably branches from g the rim-fiow-channel It at a location adjacent the infiow passage 30, n i 4 During the flushing cycle of the defecator, the

over-flow channel of the storage tank II constitutesan adequate air .vent for the rim flow channel. When the flushing cycle is initiated by opening a suitable valve (not shown), normally closing the inflow passage 30 between thestorage tank I l :and the rim-flow ch'annel 16, the liquid content or the tank I I flows unidirectionally into andaround the-rimflow-channel l6, as appears clearly from Fig 4, supplies the' down-flow con-' duit 20,-the down-flow channel. H, and. the plurality of jet openings 23 with flushing liquid, and seeks its level in the'ove'r flow channel 26. Thus, entrapment of air within the rim-flow,-

channel is precluded, as is also retardation of .fiowof liquid through such channel and through the branch channels. The overfiow channel 26' constantly affords an air vent. therefor. That liquid tending to remain in the lower portion of the overfiow channel 26 at the termination of A wall 3I' the flushing cycle, flows backwardly around the rim-flow-channel to supply the after-fill to the well of the bowl.

Whereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention as set forth in the following claims.
